Order of the atomic theorists |
Democritus, Aristotle, Dalton, Thomson, Millikan, Rutherford, Bohr, Schrödinger, Chadwick, Gellman |
|
|
What are Democritus contributions to the atomic theory |
Solid sphere model, atoms are small/indivisible and make up everything |
|
|
Aristotle contributions to the atomic theory? |
Slows down scientific research on atom by discrediting Democritus. Believes everything is made up of fire water and earth. |

Gell man contributions to the atomic theory |
Discovered Quarks |
|
|
Daltons five principles of the atomic theory |
All elements are made up of atoms, all atoms in an element are identical, atoms cannot be created or destroyed, a compound is made of two atoms chemically combined with each other, and during a chemical reaction atoms are rearranged |
